Gaming machine and game having multiple levels

ABSTRACT

A game has the potential for multiple levels. The game initiates with a base or first level of one or more symbols. If an advancing outcome is received, the game advances to a second level. In one embodiment, the game builds as successive levels are played, such as by adding one or more symbols at each level of the game. The game may comprise a video-slot type game in which a base set of one or more rows of symbols are displayed and evaluated and where an additional row of symbols is added at each successive level. Advancing outcomes of symbols may comprise designated combinations of symbols along a pay line and including certain symbol positions, such as at least one symbol in a top row of the symbol set.

This application is a continuation-in-part of U.S. application Ser. No.12/456,565, filed Jun. 17, 2009, and claims priority to U.S. ProvisionalApplication Ser. No. 61/146,791, filed Jan. 23, 2009.

FIELD OF THE INVENTION

The present invention relates to gaming machines and systems forpresenting games.

BACKGROUND OF THE INVENTION

Wager and amusement gaming continues to grow in popularity. Nonetheless,casinos and other establishments that offer wager based gaming face thechallenge of developing new and exciting games in order to maintainplayer interest. One example of a popular game which is presented inboth amusement and wager-based formats is the game of SLINGO (registeredtrademark of Slingo, Inc.). This game was originally developed well overa decade ago and is the subject of numerous patents. However, in orderto not only maintain the interest of existing players of the originalgame but to draw additional players to the game, the inventors hereinhave developed a new and exciting version of the game which implements anew game play mechanic and new game play features as compared to theoriginal game.

SUMMARY OF THE INVENTION

One aspect of the invention comprises methods of presenting and playinggames. Another aspect of the invention comprises gaming machines andgaming systems for presenting at least one game.

In one embodiment of a game, a single game has the potential formultiple levels. In one game variation, an initial symbol or symbols maybe displayed and it may be determined if the player has received anadvancing outcome. If so, the game may advance to a next or successivelevel in which at least one additional symbol is displayed and theresulting set of symbols are evaluated. The game may progress throughmultiple levels. Winnings may be awarded for advancing outcomes or forreaching certain game levels.

In one embodiment, an advancing outcome may be achieved if theparticular symbol or symbols in a set match a predetermined winning oradvancing set of symbols. In another embodiment, each level comprises asymbol matching event in which a set of base symbols are comparedagainst a set of game symbols for potential matches. If a requiredminimum number of matches or other criteria are met, the game maycontinue to the next level. In this embodiment, the game symbols may bedisplayed in rows, such as rows of a matrix having m rows by n columnsof symbol positions. The base symbols may then be displayed in a rowhaving n positions, where each base symbol in an individual n^(th)position is compared to the corresponding game symbol in the same n^(th)position.

As another aspect of the invention, successive levels of the game buildupon prior levels. A first level of the game may utilize a first or baseset of symbols. Successive levels of the game may add one or moresymbols to the base set, whereby later levels of the game are playedwith larger sets of symbols.

In one embodiment, the game is played as a wagering game. Awards, suchas credits representing monetary value, may be awarded for matches ofindividual game symbols and/or matches of patterns of game symbols.

As one example of a method of presenting one embodiment of a game, awager is accepted from a player. A first row of n game symbols is thenactivated relative to a matrix of symbol positions. A row of basesymbols having n positions is displayed. The base symbol in each n^(th)position is then compared to the corresponding game symbol in the sameposition for potential symbol matches. One or more awards may be awardedfor symbol matches. If a required number of symbol matches are notreceived relative to the first row of game symbols, the game may end. Ifa required number of symbol matches are received relative to the firstrow of game symbols, the game preferably continues by repeating thefollowing sequence until there are no unactivated rows of symbolpositions on the matrix: (1) activating a next row of game symbolsrelative to the matrix of symbol positions; (2) displaying a new set ofbase symbols; (3) comparing the base symbols and game symbols which arein corresponding positions for potential symbol matches; (4) awardingawards for symbol matches; (5) if a required number of symbol matchesare not received relative to the next row of game symbols, ending thegame; and (6) if a required number of symbol matches are received (orother advancing criteria are met) relative to the next row of gamesymbols, repeating steps (1)-(6).

Additional aspects of the invention comprise game features. The gamefeatures may be utilized with games of the invention or other games. Forexample, in one embodiment, awards for winning events in higher levelsof the game may be higher than those in lower levels of the game. Forexample, matches of game symbols in a first row may yield a first rangeof awards, while matches of game symbols in a second row may yield asecond higher range of awards.

In one embodiment, a game may include one or more wild symbols. A wildsymbol may be matched to any game symbol. In one embodiment, the wildsymbol may be a Joker which is displayed as one or more of the basesymbols. A methodology may be applied to the application of a Joker tomaximize the player's winnings. For example, Jokers may be matched toparticular game symbols in a manner which yields high award symbolmatching patterns or which match game symbols in higher levels (havinghigher awards associated therewith).

A game may also include mystery bonuses or prizes, as well as a gameadvance feature. In one embodiment, the game advances from one level toanother if a required minimum number of symbol matches are receivedrelative to a first level or row of game symbols. In another embodiment,a player might receive a game advance symbol, such as a frog, whichcauses the game to advance to the next level even if the required numberof symbol matches is not received.

As another example of a method of presenting an embodiment of a game, aninitial set of at least one symbol is displayed in a first level of thegame. If it is determined if the initial set does not include orcomprise an advancing outcome, the game may end. If the set does includean advancing outcome, at least one additional symbol is added to the setof symbols in a next or successive level. The new set of symbols is thenevaluated for an advancing outcome.

In this embodiment, the game may be a slot-type game in which one ormore rows of symbols are displayed in the initial level and one or morerows are added in each successive level. In one configuration, anadvancing outcome comprises at least one predetermined combination ofsymbols along an active pay line. Further, for the outcome to be anadvancing outcome, the combination of symbols along the pay line may berequired to include at least one symbol in a particular position or row,such as a top row. Alternatively, or in addition, an advancing outcomemay require a particular minimum number of winning outcomes per level.

A wide variety of aspects of games, gaming machines and game featureswill be appreciated from the description herein. As detailed herein, oneor more games offer a player substantial excitement relative to thepotential of advancing through multiple levels of a game. Thisexcitement is enhanced when the game is played as a wagering gameoffering the player opportunities for winnings.

Further objects, features, and advantages of the present invention overthe prior art will become apparent from the detailed description of thedrawings which follows, when considered with the attached figures.

DETAILED DESCRIPTION OF THE INVENTION

In the following description, numerous specific details are set forth inorder to provide a more thorough description of the present invention.It will be apparent, however, to one skilled in the art, that thepresent invention may be practiced without these specific details. Inother instances, well-known features have not been described in detailso as not to obscure the invention.

One aspect of the invention comprises methods of presenting and playinggames using symbols or indicia. One embodiment of a game is a symbolmatching game in which one or more sets or rows of base symbols arematched to sets or rows of game symbols. Another embodiment of theinvention is a game having one or more levels or parts, including wherea player must obtain certain game results in order to advance tosuccessive parts or levels of the game. Yet another aspect of theinvention is game where symbols are added during portions or levels ofthe game. Other aspects of the invention comprise gaming machines andsystems for implementing or presenting the games of the invention.

FIG. 1 is a flow diagram illustrating one embodiment of a method of gameplay/presentation in accordance with the invention. As described below,this embodiment of the game includes both a symbol-matching feature anda game advance feature.

In one embodiment, a game of the invention is presented as a wager-basedgame. Thus, in accordance with a step S1, a player may place a wager.Such a wager may be accepted by a game operator, such as at a gamingmachine. As indicated below, the wager might comprise money, chips,tokens, credits or the like having physical form or merely representedelectronically.

In accordance with the game, in a step S2, a first set of game symbolsis displayed or made active related to a first set of positions.Preferably, the first set of game symbols comprise a sub-set of a largerset of symbols, or comprise the random distribution of a set of symbols.Such symbols may have various forms and may comprise letters, numbers,words, images or the like. In one embodiment, the symbols in the set ofsymbols may all be unique. In preferred embodiments, one or more of thesymbols in the set of symbols may be duplicated or repeated. Forexample, the first set of game symbols may comprise five (5) symbolsselected from a larger set of fifteen (15) symbols. In one embodiment,the first set of game symbols is displayed in a row of n columns.Preferably, there are at least 1 and more preferably, at least 5,columns.

In a step S3, a set of base symbols is displayed for matching to thefirst set of game symbols. In a preferred embodiment, the set ofgenerated base symbols is equal in number to the symbols in the firstset of game symbols. For example, if the first set of game symbolscomprises a row of five (5) symbols, the set of base symbols comprisesfive (5) symbols. Preferably, the set of base symbols is randomlygenerated.

In a preferred embodiment, symbols in the first set of game symbols andthe set of base symbols are compared positionally. In one embodiment,the first set of game symbols and the set of base symbols are arrangedinto a row of n columns, and the symbols in each n^(th) column arecompared with one another.

In one embodiment of the game, the object is to match as many of thebase symbols and game symbols which are in corresponding positions, aspossible. As detailed below, awards may be provided for matches.Preferably a match occurs if the symbols in corresponding positions arethe same.

In one embodiment of the game, if certain game criteria are met, thenthe game continues on to a next level or portion of the game. Thisfeature may be referred to as a “game advance” feature. In a preferredembodiment, in a step S4, if a certain minimum number of matches areachieved relative to the first set of game symbols, the game continueswith play of a second set of game symbols. For example, a player may berequired to achieve at least one match relative to the first set of gamesymbols to advance the game to the next level and play the second set ofgame symbols. In that event, a second set of game symbols is displayedor rendered active, as in a step S5. Preferably, the second set of gamesymbols comprises the same number of symbols as the first set of gamesymbols. For example, the second set of game symbols may comprise a rowof n columns of symbols. The second set of game symbols may be displayedadjacent the first set of game symbols, such as in a matrix directlyabove the first set of game symbols.

As illustrated in FIG. 1 and as described in more detail below, in oneembodiment, the criteria for advancing might comprise other than aminimum number of matches. For example, the game might advance if aplayer received a particular special symbol, such as a “frog” whichsymbolizes entitlement of the player to leap or advance automatically tothe next row or level. In such a configuration, the game may include anadditional step, such as a step S4A in which a determination is made asto whether such additional criteria for advancement have been met.

Another set of base symbols is then displayed for matching to the secondset of game symbols, as in a step S6. Preferably, this set of basesymbols is randomly selected and so may differ from the first set ofbase symbols. Once again, the generated base symbols are compared to thesecond set of game symbols for potential matches. Awards may again beprovided for matches. If a certain minimum number of matches areachieved relative to the second set of game symbols (or, as detailedbelow, other criteria are met), as in a step S7, the game may continueto a third set of game symbols. This process may repeat until all of thesets of game symbols are displayed, as in a step S8. For example, in oneembodiment, a total of m rows by n columns of symbols may be displayedin a matrix format. The first set of game symbols may comprise a firstrow of n columns of symbols; the second set of game symbols may comprisethe second row of n columns of game symbols, and so on. In a preferredembodiment, there may be twenty-five (25) symbols arranged into a fiveby five (5×5) matrix.

If the player successfully advances through all of the levels of thegame and/or if the requisite number of symbol matches are not received,then awards received for the game may be paid, as in step S9. Asdescribed in greater detail below, awards may be provided for symbolmatches or other events. In one embodiment, the awards may comprisecredits. The awards might also or instead comprise points, tangiblegoods, discounts, tickets, money (such as coins or paper currency) orthe like. The game may then end at a step S10.

In accordance with the invention, a game is provided which includes agame “advance” feature. In particular, a single game has the potentialto comprise multiple levels or portions. If a player achieves certainthresholds or requirements, the player may advance or move from a firstlevel of the game through additional levels of the game. In this manner,a player is enticed to try and reach the final stage or level of thegame. Further, the play of the game in levels progressing from a firstlevel to a final level enhances the excitement of the game.

One embodiment of a preferred embodiment of a game in accordance withthe invention will be described with reference to FIGS. 2A-2D. Referringto FIG. 2A, in one embodiment of the game, game information is displayedto a player. As detailed below, this game information might be displayedas a graphical user interface by a video display, such as a display of agaming machine or computer.

In one embodiment, the game information comprises sets of game symbolsto be matched, sets of generated base symbols, and bet and wininformation, among other information. In one embodiment, a matrix 20 ofsymbol positions is displayed. In a preferred embodiment, the matrix 20has five (5) rows and five (5) columns for a total of twenty-five (25)positions.

In one embodiment, each of the positions of the matrix 20 has anassociated symbol or indicia. Preferably, the symbols are randomlyselected, such as by one or more random number generators. As detailedbelow, at the start of the game, only a first row 40 of symbols isactive. Thus, the other symbols associated with the matrix may not yetbe displayed or might be displayed in a different fashion (such as in ashaded fashion as shown in FIG. 2A). Likewise, the first row 40 ofsymbols may be highlighted or displayed in a manner indicating thatthose symbols are active.

In one embodiment, the symbols in the matrix may be referred to as the“game symbols” of symbols, in that these symbols do not change duringthe play of the game.

The game information also includes sets of symbols to be matched to thegame symbols. In one embodiment, a row of base symbols 28 is displayed.In a preferred embodiment, this set of symbols 28 may change during thegame. Preferably, there are a number of base symbols equal to the numberof symbols in each set of game symbols, such as equal to the number ofcolumns in the matrix 20. Thus, where the matrix 20 has five (5)columns, there are five (5) base symbols. In a preferred embodiment, thebase symbols 28 are arranged into a row positioned below the matrix 20.

A payout range 22 may be indicated relative to one or more of the gamesymbols. In one embodiment, a payout range 22 is indicated relative toeach row of symbols. For example, such may be indicated to the left orright side of each row of the matrix 20. The payout range 22 mayindicate one or more values or a range of values for awards for matchesof the designated symbols (such as the symbols in that row).

An award total 24 may be indicated. In one embodiment, an award total 24may be indicated relative to each row of symbols, such as to the rightof each row of symbols.

A variety of other information may also be displayed to the player. Forexample, various bet amount buttons 26 may be provided. These bet amountbuttons 26 may permit a user to place wagers in particular amounts, suchas amounts of 50 credits, 100 credits or the like, including a “max bet”which permits the player to place the maximum wager allowed by the game.

The interface may also display information such as the total number ofcredits belonging to the player 36, the number of credits won by theplayer for a particular portion of the game 37, a total win for the game38, and a number of free spins 60.

In one embodiment, the game may offer one or more bonus awards. Such maycomprise progressive awards which change in value over time. Informationregarding these various awards may be displayed, such as in aprogressive jackpot window 30 at the top of the interface.

Of course, the arrangement, content and appearance of the interface mayvary. For example, the interface may utilize various artwork such ascolors and themes. The size of the interface and the arrangement of thefeatures thereof may vary.

As detailed below, a player may provide input to the game in variousmanners. In one embodiment, such may be by input to a touch screenrelative to one or more of the buttons or areas of the interface. Inputmight also be provided to external devices such as physical buttons orthe like.

In one embodiment, game play begins by a player placing a wager. In oneembodiment, this may be by the player providing input to one of the betamount buttons 26. Game play may then automatically be initiated or itmay be initiated, by a player providing input to a “spin” or similarbutton 32. In one preferred embodiment, if a player places a maximumwager, such as by pressing the “MAX BET” button, the game automaticallystarts. On the other hand, if a player places a wager less than themaximum wager, such as by placing a wager of an amount such as 50, 100,150, etc. credits, then the player may be required to also press theSpin button 32 to then start the game.

In a first portion or level of the game, only a first row 40 of thematrix 20 is active. As indicated above, the symbols of that row 40 maybe highlighted or otherwise designated to indicate to the player theactive status thereof. In one embodiment, the player is also providedwith information regarding the number of matches to the symbols of thefirst row which are necessary to advance in the game and the value ofawards for matches. In one embodiment, one or more matches are requiredto advance past the first level of the game.

A set of base symbols 28 is displayed, such as below the first row 40 ofgame symbols. The base symbols 28 may be displayed in alignment with thesymbols in the first row 40. Preferably, the symbols in correspondingpositions of the base symbols 28 and the first row 40 of game symbolsare compared to determine if they match. In the embodiment illustrated,this comprises comparing the symbols in the same columns 50, 52, 54, 56,58. Thus, the symbol in the first position of the base symbols 28 iscompared to the symbol in the first position of the first row 40 ofsymbols (i.e. the symbols in the first column 50 are compared). If thesymbols match, a match may be declared or indicated, such as byhighlighting the matched symbol in the first row 40. In the exampleillustrated in FIG. 2A, the base symbol “15” is compared to game symbol“14” in the first column 50, the base symbol “17” is compared to thegame symbol “17” in the second column 52, the base symbol “44” iscompared to the game symbol “36” in the third column 54, and so on.Obviously, in this example, the only base symbols “17” and “70” matchcorresponding game symbols “17” and “70” in the second column 52 andfifth column 58. Such a match may be indicated by highlighting the gamesymbol, showing a new symbol in that symbol location or the like.

As indicated above, the game may be played with a variety of symbols.Such may comprise numbers, letters, icons or images, or combinationsthereof. In one preferred embodiment, the game is played with thenumbers 1-75. The numbers 1-15 are used relative to the first column,the numbers 16-30 are used relative to the second column, and so on.Thus, one or more random number generators may be used to select anumber from the group 1-15 for each of the positions in the firstcolumn. In one embodiment, the numbers in each column are unique. Inthis configuration, the sets of base symbols are selected from the samegroups of numbers. For example, each time a set of base symbols isgenerated for matching to each row of game symbols in the matrix, thebase symbols are selected from the set 1-15 as to the first position,16-30 as to the second position, etc.

In one embodiment, awards are randomly generated and assigned to eachposition in the matrix 20. The awards may be selected from the indicatedvalue range 22. For example, relative to the first row 40 of gamesymbols, awards may be randomly selected from the range of 5 to 20credits for each symbol position. In a preferred embodiment, the rangefor each row or level of the game increases relative to the previous rowor level, and the particular awards or ranges are preferably higher forgames where the player places a higher wager.

In the event of a match, the number of credits (or other value, award oradditional game feature) which was assigned to that symbol position ispreferably awarded to the player. The particular award for a match maybe shown, such as in the matrix 20 adjacent to the symbol which wasmatched, as illustrated in FIG. 2A. In one embodiment, the symbol thatwas matched may be removed from the matrix 20 and the winning award maybe indicated in its place. In addition, the total of the awards for aparticular row or level may be indicated in the award total area 24 forthe row.

In the event a player meets the required criteria for the first level,the player may advance to a second level of the game. In the preferredembodiment, as indicated, this criterion comprises a minimum number ofsymbol matches. As described above, however, a player might advancebased upon other criteria, such as the appearance of a game advancesymbol.

If the player does not meet the required criteria, such as the requiredminimum number of symbol matches, the game preferably ends. If theplayer does meet the required criteria, the game preferably moves oradvances to the next portion or level of the game. Preferably, at thistime, a second row 42 of game symbols becomes active, as illustrated inFIG. 2B. Again, the game symbols in the second row 42 may at that timebe highlighted or another designation may be provided to the player toindicate that those symbols are active.

A second set of base symbols 28 is then generated for comparison to thesecond row 42 of game symbols. The second set of base symbols 28 ispreferably again randomly selected and compared position by position tothe game symbols in the second row 42. As with the first row 40, matchespreferably have associated awards and the total of the awards for therow may be indicated to the player.

In a preferred embodiment of the invention, once a row or level of gamesymbols has been activated, the row or level remains active and can bematched through the entirety of the game. In this manner, a player mayreceive matches relative to symbols in earlier activated rows or levelsand receive additional awards, including improving the probability ofreceiving patterns or combinations of matches across multiple rows orlevels. For example, as illustrated in FIG. 2B, the number “36” in thesecond set of base symbols 28 does not match the corresponding number“43” in the second row 42 of game symbols, but it does match number “36”in the previously activated first row 40 of game symbols. As a result,an additional award of 5 credits has been paid to the player for thatmatch.

Once again, if certain criteria are met, the game preferably continues.In one embodiment, this again comprises a certain minimum number ofmatches. Preferably, this number is equal to or greater than thatrequired to advance from the first row 40 of game symbols. For example,a single match may be required to advance from the first row 40, and twomatches may be required to advance from the second row 42. If such arequirement is not met, the game preferably ends. If the requirement ismet, the game preferably continues or advances to the next level.

In the configuration illustrated where there are five (5) rows, thisgame preferably continues in this fashion by the game either ending orcontinuing to the next level to a third row 44, a fourth row 46 and afifth row 48, as illustrated in FIG. 2C. Once the game reaches the fifthrow or level and matches are determined relative to the fifth row 48,the game ends. Again, when the player advances to the next level or row,a new set of base symbols 28 is generated and displayed for comparisonto the current active row of game symbols.

Additional aspects of the invention will now be described in detail.

In one embodiment, a player keeps accrued winnings even if the game endsbefore the player reaches the final level. Thus, for example, if theplayer won 10 credits by matches relative to the first row 40, theplayer would retain those winnings regardless of how far the playeradvances in the game. In other embodiments of the game, however, theplayer might be required to reach the final level in order to win theawards accrued during the game.

In a preferred embodiment, the game comprises a single game withmultiple levels. Thus, when a player places at least a minimum wager,the player has the opportunity to play the game through all of thelevels without any additional wager. In other embodiment, the playermight be required to place a wager to continue through each level.

In one embodiment, the game may include other types of awards. Forexample, awards might be represented by secondary symbols in the eventof a match. In one embodiment, one or more gold coins (or other symbols)might be associated with game symbols or game symbol positions. If theplayer receives a match as to that symbol or that position, then thegold coin may be displayed to the player. Instead of a normal award, theplayer may receive a higher than normal award for that match. In oneembodiment, that award might comprise a randomly selected value (such asfrom a pre-defined set of values like 10, 25, 50, 75, 100 or 200credits). Such a value might be awarded directly, or it might bemultiplied by the player's wager.

In one embodiment, a player may be awarded one or more free spins. Suchspins may be indicated in a free spin area 60 of the interface. Freespins may be awarded based upon various criteria, including randomly andas a secondary award to a symbol match. In one embodiment, a player mayutilize a free spin to obtain another set of base symbols relative to aparticular level of the game. For example, a player may advance to thesecond level of the game, wherein the second row 42 of game symbols isactivated. After a set of base symbols 28 is generated or activated, theplayer might have received only a single match. If two matches arerequired to advance from the second level to the third level of thegame, the game would normally end. However, if the player has a freespin, the player may use that spin and to cause another set of basesymbols 28 to be generated. That extra set of base symbols may result inadditional matches of the game symbols in the second row 42. If so, thegame may then advance to the next level (third row).

In one embodiment, if a player reaches the final level and the playerhas one or more free spins remaining, the free spin(s) may be used andthe extra set of base symbols may be generated and may be compared tothe game symbols in any of the rows or levels. This may result inadditional matches and additional awards.

In one embodiment, a player may receive awards for combinations ofsymbol matches. In a preferred embodiment, a player receives an awardfor matching all of the symbols along a single row, a single column or adiagonal of the matrix. Such a combination of matches may be referred toas a SLINGO (registered trademark of Slingo, Inc.). The awards for suchcombinations of matches may vary. In one embodiment, the award for adiagonal SLINGO combination is higher than that for a verticalcombination, which is in turn higher than that for a horizontalcombination.

Further, awards might be provided for other patterns or combinations ofsymbol matches such as an “X” pattern as illustrated in FIG. 2F, orother patterns such as “four corners” or the like. Such patterns mightvary depending upon the arrangement or configuration of the gamesymbols.

FIG. 2C illustrates an example of the game where a player has advancedto the final level. As a result of the comparison of another set of basesymbols 28 to the last row of game symbols 48, the player has completeda SLINGO combination in the form of a set of symbol matches along one ofthe diagonals through the matrix 20.

As indicated above, the interface may be configured to display a jackpotwindow 30. That window may display the amounts of one or more jackpots.The jackpots may comprise large payouts for particular events, such asthe receipt of particular combinations of symbol matches. The jackpotsmight comprise fixed amounts or comprise variable amounts. For example,one or more of the jackpots might comprise progressive jackpots. Suchjackpots may grow in value over time. The jackpots may be funded invarious manners. For example, the jackpots may be funded from a portionof wagers at one gaming machine or a plurality of gaming machines, as isknown in the art.

The game may include a variety of other features. In one embodiment, aplayer may be permitted to advance to the next level even if the minimumnumber of symbol matches is not obtained. In one embodiment the game maybe configured to randomly generate an “advance” symbol relative to oneor more of the symbols. The advance symbol might comprise a “frog”symbol. If the symbol is generated relative to a particular row, thenthe play of the game preferably automatically advances to the next levelor row. In one embodiment, such a symbol may be received relative to anyrow except the last (fifth row 48 in this case). In a preferredconfiguration, if such a symbol were assigned to a position in the fifthrow and a match occurred relative to that position thus triggering thesymbol, the symbol is instead treated as a free spin award. In thatevent, the frog symbol would not appear, but instead the number of freespins would be incremented in the free spin area 60.

FIG. 2E illustrates one example of such a feature. As illustrated,relative to play of the second row 42, the player received only a singlematch of a base symbol 28 to a game symbol, that of the number “54” inthe fourth column. Normally, this would result in the game endingbecause the player did not receive the required minimum number of 2symbol matches. However, in this example, the player received the “frog”symbol in the set of base symbols 28. This symbol resulted in the gameautomatically advancing to the next row or level of the game (see stepS4A of FIG. 1). In another embodiment, instead of such a symbolappearing as one of the base symbols 28, the symbol might be associatedwith a symbol position in the matrix 20, wherein if that symbol ismatched, the “frog” or other advance symbols is released (for example,the “frog” symbol might have been associated with the number “54” in thematrix, such that when that number was matched, the “frog” symbol wasreleased and displayed, causing the game to advance).

In one embodiment, the game may include wild symbols. Such symbols mightcomprise, for example, a Joker, as illustrated in FIG. 2D. In oneembodiment, a Joker which is displayed as one of the base symbols may bematched to any active game symbol. In one embodiment, there is apreferred hierarchy for determining which game symbol a Joker will beapplied to as a match. There are often several combinations of rowswhere each Joker can be applied or matched. In one embodiment, thegaming machine evaluates (such as by a sub-routine) each validcombination and assigns a point score to each one to determine which onewill maximize the player's winning payout. Each possible combination ofJoker placement is evaluated for the following:

1) If a combination completes a progressive jackpot pattern, then thiscombination is given top priority;

2) If a combination enables the player to advance to the next row, thiscombination is given second priority;

3) If a combination completes one or more designated or selected symbolcombinations, such as on or more SLINGO combinations (i.e. one or morerows, columns, or diagonal matches), then that combination is giventhird priority. The more of such combinations that are completed, thehigher priority it gets over other combinations of this kind; and

4) Otherwise, a Joker(s) is placed in the highest row(s) possible.

In the event that two combinations are given equal priority, the routinewill assign a point score to each Joker according to which row eachJoker in the combination will be placed in. The higher the row, thehigher the score.

As one example, a Joker may be displayed in the first and thirdpositions or columns of the base symbols. Assume that the first Jokercan only be placed at either the second, third or fourth row and thatthe middle Joker can only be placed in the third row. Also, assume thata criss-cross progressive jackpot would be completed if the centerposition of the matrix were completed (which is the only position thesecond Joker can be placed). In this event, there are three possiblecombinations:

1) First Joker placed at row two, second Joker placed at row three;

2) First Joker placed at row three, second Joker placed at row three; or

3) First Joker placed at row four, second Joker placed at row three.

Each combination will complete the criss-cross pattern. However, inaccordance with the above-described preferences, two points are assignedto the first combination since the first Joker will be placed in thesecond row, three points for the second combination, and so on. Thethird combination would thus ultimately be chosen since it completes thecriss-cross pattern while maximizing the player's winnings by placingthe non-pattern-completing Joker at the highest row possible (sincewinnings for symbol matches have a higher range for higher levels orrows).

FIG. 2D illustrates another example of the placement of a Joker. In thiscase, the player has advanced to the last level of the game and isplaying the fifth row 48 of game symbols. As illustrated, the firstsymbol of the base symbol set 28 is a Joker. The Joker could be placedin the fourth row 46 and complete a winning SLINGO combination alongthat row. However, a better result is obtained for the player by placingthe Joker in the fifth row 48, since that placement then both completesa SLINGO combination (a diagonal) and results in placement of the Jokerin a higher level or row, thus resulting in potential higher winningsfor the player.

When determining the best combination, it is important to note that thegaming machine can account for matches made by other base symbols. Allother symbol matches are processed first, even though they may be madesubsequent the positions with Jokers.

In another embodiment of the invention, a game may include a mysterybonus. Such a bonus may be indicated by an animated character such as aCherub. The Cherub may appear randomly, such as by being displayed onthe interface after a set of base symbols are displayed or after aplayer has unsuccessfully completed a level (so that the game wouldotherwise end). In one embodiment, the Cherub could result in additionalawards to the player and potentially prevent the game from ending. Whenthe Cherub is displayed, it could do some or all of the followingfeatures: (1) match game symbols of the matrix 20; (2) add Jokers to thebase symbols 28; (3) automatically advance the player to the next row orlevel of the game; and (4) award one or more free spins (such as byincreasing the free spin count in the free spin area 60), thuspermitting the display of a new set of base symbols.

As one example, the Cherub could be displayed on the screen and beconfigured to randomly select symbols for matching to the active gamenumbers displayed in the matrix 20. Such additional matches yieldadditional winnings to the player and may result in the player receivinga required number of matches as to the current row to advance to thenext level/row. For example, the Cherub might be animated and use a wandto select particular displayed game symbols, at random, thatautomatically are designated as matches (even though they were nevermatched by a base symbol).

As another example, the Cherub could be displayed on the screen and beconfigured to add one or more Jokers to a base symbol set. Those Jokerscould then be used to match one or more game symbols as in the mannerabove, again triggering additional awards for a player and potentiallyresulting in the player advancing to the next game level. The Cherubmight add a single Joker or multiple Jokers. For example, the Cherubmight be animated and use a wand to convert already displayed basesymbols (such as numbers) into Jokers.

As another example, the Cherub could be displayed on the screen andaward a player a free advance to the next level/row. When the Cherubdoes this; the matrix will increase by one (1) row and the player willautomatically be given another spin, thus receiving an additionalopportunity for matches. This feature would only be active if the playerhas not already reached the final level or row.

As a final example, the Cherub could be displayed on the screen andcause another set of base symbols to be displayed relative to aparticular row of game symbols (i.e. a “free spin”). The new basesymbols may result in additional matches of game symbols in the activerow, yielding additional awards and potentially advancement to the nextlevel/row. For example, the Cherub might be animated to use a wand tocause the base symbols to rotate or spin to a new set of base symbols.

The Cherub may be configured to appear only appear once during the gameand may accomplish one or more features, such as those described above.In order for the Cherub to be active, a player may be required to placea wager of a certain size. In another embodiment, the player may berequired to place a side of bonus wager in order to activate thefeature. For example, the player might be required to place anadditional wager of 50 credits to activate the feature above and beyondthe base wager the player places.

As indicated, a player may be permitted to place wagers in variousamounts. In one embodiment, the size of a player's wager may determinethe number of game features which are activated. For example, a wager of50 credits may activate the “Jokers” feature; a wager of 100 credits mayfurther activate the “Gold Coins” feature; a wager of 150 credits mayactivate the “Frog” feature; a wager of 200 credits may activate the“Free Spins” feature; and a maximum wager of 250 credits may activatethe “Jackpots” feature. Of course, the size of the wagers and the typesof features which are activated may vary.

In one embodiment, presentation of the game may be automatic and may notrequire player input beyond the player being required to place a wagerand, in some embodiments, starting the game via the “spin” button or thelike. For example, the game may automatically display the base symbolsand compare those symbols to the first row of game symbols and indicateany matches. If the required number of matches is received, the game mayautomatically move to the second level, etc. In other embodiments,however, the player might be required to provide various inputs. Forexample, a player may be required to compare the base symbols to thegame symbols and indicate matches, such as by providing input to a touchscreen proximate to a matching symbol. A player might also be requiredto provide a “spin” input in order to initiate each level of the game. Aplayer might also be required to provide input to utilize a free spin.

It will be appreciated that the game may comprise the play of variousnumber of game symbols. For example, instead of a 5×5 matrix of gamesymbols, the matrix might be a 4×2, a 6×7, a 3×5, a 4×4, or an 8×8matrix or the like. In addition, the number of game symbols in differentrows could potentially vary. For example, there might only be three (3)game symbols in the first row, four (4) in the second row, and so on. Insuch event, the number of base symbols which are displayed may vary tomatch the corresponding number of game symbols in the active row.

It will also be appreciated that while the game may advance through rowsof a matrix starting at the bottom of the matrix and working upwardly,the game might advance in other manners. For example, the rows could beplayed from top to bottom. In another embodiment, the sets of game andbase symbols might be displayed in completely different fashions otherthan the displayed matrix configuration.

In one embodiment, the base symbols may be referred to as “spun”symbols. In particular, as detailed below, the base symbols might bedisplayed by one or more mechanical spinning reels. Alternatively, theymight be displayed in graphical from via a video display in a mannerwhich makes it appear that symbols are spinning and stopping atpositions to display the base symbols. Of course, the base and gamesymbols may be displayed in various manners and via various mechanisms.

As indicated above, one aspect of the invention is a game havingmultiple levels and an “advance” feature. In particular, a game isconfigured to have multiple parts or levels. Preferably, a player ispermitted to play a first part or level of the game and must thenadvance to the other parts or levels. Certain criteria may be requiredto be met in order for the player to advance. As indicated above, thecriteria for advancing from one level to a next level may be a winningoutcome. In one embodiment, the game may have a plurality of parts orlevels and the player may attempt to advance through the parts or levelssuccessively.

Yet another aspect of the invention is a game having multiple levels orparts where the game builds through such levels or parts. In oneembodiment, a first or initial set of symbols are used in a first levelof the game. Those symbols are used in later successive parts or levelsof the game, such as by adding one or more symbols in each additionallevel. In this manner, later levels or portions utilize larger sets ofsymbols.

Another embodiment of a game having the advance and building featureswill be described with reference to FIG. 3. In this embodiment, the gamedoes not have a symbol-matching feature like the game above, but isinstead a slot or video poker type game in which a player attempts toachieve certain combinations of symbols.

Once again, the game is preferably played as a wagering game. As such,in a step S1, a player may place, and the game operator/machine mayaccept a bet or wager.

After a wager or bet has been placed, a base or initial set of one ormore symbols are displayed to a player, as in step S2. As indicatedherein, the symbol(s) may be displayed by a video display, reels, onphysical elements such as cards or other objects. In one embodiment, thegame is a video slot-type game in which symbols are displayed by a videodisplay of a gaming machine. However, the game might be a video pokertype game, or rotating reel, physical card, or other type of game.

The base set of symbols might comprise as few as one symbol or a set ofsymbols, such as two symbols. The symbols may be arranged in variousconfigurations or patterns, such as randomly, in a row, a column, amatrix (of rows and columns), a pyramid, etc. For example, the set ofsymbols might comprise a row of two or more symbols or a column of twoor more symbols.

The one or more symbols in the base set of symbols may be selected froma group of symbols. Such a selection is preferably random, such as byusing a random number generator, by random dealing, by random rotationof reel(s), etc. (and wherein the symbols may be displayed in variousfashions such as by one or more video displays, physical reels, cards orthe like). For example, the base set of symbols might comprise a singlesymbol selected randomly from a group of two or more game symbols.

In a step S3, it is determined if an outcome of this first part or levelof the game is an advancing outcome. In one embodiment, this stepcomprises determining if the player has received an advancing outcomefrom the base set of symbols.

In one embodiment, one or more symbols or combinations thereof may bedeemed advancing combinations or outcomes. Preferably, the one or moreadvancing outcomes or combinations are fewer than all possible outcomesor combinations. Thus, for example, if the base set of symbols comprisesa single symbol selected from a group of ten possible symbols, one ormore of the particular symbols (but not all ten) may be deemed advancingsymbols. When the base set comprises multiple symbols, advancingoutcomes may comprise one or more symbols. In one embodiment, the one ormore advancing symbols may be required to appear or be located incertain positions or combinations, such as along a designated pay lineincluding one or more particular symbol positions. As also detailedbelow, an advancing outcome might require multiple winning combinations.

If a player does not receive an advancing outcome, then the gamepreferably ends, as in a step S4. In that event, the player may losetheir wager and receive no corresponding winnings or awards for playingthe game. In another embodiment, as detailed below, a player mightreceive a winning outcome but not an advancing outcome. In such event,the player might be paid winnings for the winning outcome but the gamemight otherwise end (and not progress to the next level).

In one embodiment, advancing outcomes and/or winning outcomes may bedesignated by a pay table. Such a pay table may designate associatedwinnings or awards for those outcomes. In a step S5, if the playerreceived an advancing outcome, the winnings or awards for that outcomemay be paid to the player. Such might comprise awarding a number ofcredits, points or the like to the player, such as based upon the paytable.

As indicated above, the game preferably has the potential for multipleportions or levels. As such, in a step S6 it may be determined whetherthe game has reached its final portion or level (in the preferredembodiment, this would never be true after the base level). If so, thegame may end as in step S4.

If not, then in a step S7, the game preferably advances to the nextlevel. In a preferred embodiment this comprises displaying at least oneadditional symbol in addition to the base set of one or more symbols.For example, if the base set of symbols comprised a single symbol, atleast one additional symbol might be added to that base symbol. In otherembodiments, such might comprise displaying an additional row, column orother group of symbols relative to the base set of symbols. For example,as detailed below, in slot-type game, the base set of symbols mightcomprise a row of symbols and when the game advances, another row ofsymbols may be added. In this regard, in a preferred embodiment of thegame, as the game advances the game is played with a growing or buildingnumber of symbols (at each level one or more new symbols are added).

In a step S3, that portion or level of the game is then evaluated againto determine if an advancing outcome was received and the game thenrepeats in the manner detailed above.

Additional details of the invention will be appreciated from thefollowing example of the game. It will be appreciated that this ismerely an example and the game may be implemented in various fashions asdetailed herein.

As illustrated in FIG. 4A, the game may be implemented as a video slottype game. In this embodiment, symbols may be displayed by one or morevideo displays of a gaming machine. As illustrated, a base set ofsymbols may comprise three rows of five columns, i.e. a matrix of 3×5,for a total of 15 base symbols.

In order to advance from the first or base level to the next or secondlevel, a player may be required to obtain at least one advancingcombination of symbols. In one embodiment, the advancing combination ofsymbols comprises a predetermined combination of symbols along one ormore designated pay lines and that includes at least one symbol in thetop row.

In one embodiment, multiple pay lines may be designated. The number ofpay lines which are active may depend upon the size of a player's wager.As indicted below, certain combinations of symbols may be designated aswinning combinations if they appear along an active pay line. Inaddition, however, if such a combination occurs along one or more activepay lines which include at least one designated symbol position, such acombination may be designated to be an advancing outcome. Alternately,or in addition, as detailed below, an advancing outcome for a particularlevel may require a particular number of winning outcomes. The number ofwinning outcomes necessary to comprise an advancing outcome may increasefor higher levels of the game. For example, an advancing outcome mightcomprise at least one winning outcome (such as one along a pay lineincluding certain symbol positions) in a first level, while an advancingoutcome might comprise at least two winning outcomes in second level ofthe game.

As one example, a winning combination might comprise at least four Kingsalong an active pay line. Moreover, such a combination received along apay line which includes at least one position in the top row of the setof symbols may comprise an advancing outcome. As one example, one payline might comprise the first two symbols in the bottom row, the middlesymbol in the top row and the last two symbols in the bottom row. Asillustrated, the player has received an advancing outcome because theplayer received four Kings along the active pay line, and at least aportion of the advancing combination (one of the Kings) was present inthe top row.

As indicated above, the player might receive a winning outcome which isnot an advancing outcome. In such event, the player might receivewinnings, but then the game may end.

Of course, a wide variety of other outcomes might be designated asadvancing outcomes. For example, while it is preferred that an advancingoutcome comprise a particular combination of symbols along a pay lineand including at least one symbol in a particular position (such as atop row), it is possible that the advancing outcome might comprise otherdesignated outcomes. Those outcomes might comprise a sub-set of thewinning outcomes. For example, an advancing outcome might comprise asingle symbol in a particular designated position.

As indicated, the advancing outcomes may comprise a winning outcomehaving an associated award. For example, the designated “four Kings”outcome may have an associated award, in which case the player may bepaid winnings, such as a number of credits. In one embodiment, the awardfor an advancing outcome might be higher than for the same combinationof symbols which is merely a winning outcome (i.e. the combination offour Kings along an active pay line which does not define an advancingoutcome might have an associated award of 20 credits, while such acombination as comprising an advancing outcome might have an associatedaward of 30 credits).

If an advancing outcome is received, the game advances to the nextlevel. Since such a result was achieved, as illustrated in FIG. 4B,another row of symbols may be displayed. In a preferred embodiment, thenext row of symbols are displayed in addition to the base symbols,whereby the game is then played with a matrix of 4×5, or 20, symbols.Once again, one or more outcomes may be designated to be an advancingoutcome. Those outcomes may be the same or different as the advancingoutcomes designated for the first level.

In one embodiment, in order for a player to advance from the second to athird level, the player must obtain multiple winning combinations, atleast one of which must include at least one symbol in the top-most row.For example, an advancing outcome might comprise the combination of“five Queens” along an active pay line which includes at least onesymbol in the fourth or (newest) top row and at least one other winningoutcome, such as a Full House along any active pay line.

As illustrated, the player has five Queens along a pay line includingthe first three symbols in the first row and the last two symbols in thefourth or top row. In addition, the player has received a Full Housealong the top pay line or row. As such, the player has again received anadvancing outcome. As such, the player may again be paid winnings or anaward.

Of course, the game could end after the second portion or level.However, in this embodiment, the game advances to a third and finallevel. As illustrated in FIG. 4C, a fifth row of symbols may then bedisplayed relative to the original symbols. At this time, there is amatrix of 5×5, or 25, symbols. As there are no more levels to the game,in this final level it may be determined if the player received awinning outcome or set of symbols. Such might comprise at least “fourTens” along a designated pay line and three 7s along a pay line. Asindicated, the player has received three such outcomes. The player maythen be paid the award or winnings associated with those outcomes.

A variety of aspects of the game will be appreciated. In one embodiment,a player may receive an award, such as winnings, for each advancingoutcome. Alternatively, a player might be paid winnings only forachieving or reaching a predetermined portion or level of the game. Forexample, a player might not be paid winnings for advancing from the baseor first level to the second level, but might be paid only for reachingthe final level. Further, while awards might be associated withparticular advancing and/or winning outcomes, awards might also be paidbased upon a player reaching a particular portion or level (such as Xcredits for reaching the second level and Y credits for reaching thethird level), regardless of the particular advancing outcomes. Also, aplayer might receive an award for particular outcomes at each level andthen a bonus award based upon the highest level achieved by the player.

The advancing outcomes and associated awards might vary depending uponthe particular level of the game. For example, one set or pay table ofadvancing outcomes and associated awards may apply to the base or firstlevel, another set or pay table may apply to the second level, etc. Inone embodiment, one or more of the awards at each level may increase.Further, as indicted above, different winning and advancing outcomes maybe defined, including at each particular level of the game.

In a preferred embodiment, the game is played as a single game with asingle wager. As indicate above, however, the amount of the wager mayvary. For example, the size of a player's wager may determine which paytable(s) apply, and thus how many advancing outcomes are designatedand/or the size of their associated awards (for example, awards foradvancing outcomes may be larger if a player places a larger wager).

As also indicated, the size of a player's wager might determine thenumber of pay lines which are activated, and thus the potential forwinning and/or advancing outcomes to be received. For example, if aplayer places a minimum wager only a minimum number of pay lines, suchas 5 lines, might be activated. This might make it more difficult forthe player to obtain an advancing outcome. However, if a player places amaximum wager a maximum number of pay lines, such as 50 lines, might beactivated. This may greatly increase the probability that the playerwill achieve an advancing outcome. In either event, a player's wagerpreferably permits the player to play the entire game (through as manylevels as the player is able to advance), though the number of activepay lines per level may be determined by the size of the player's wager.

In the preferred embodiment the game has at least two portions orlevels, and more preferably three or more portions or levels. Forexample, the game could comprise two levels. A player might attempt toadvance from the base or first level to the second level. The playermight then only have the opportunity for receiving a winning outcomerelative to the second level (i.e. no advancing outcomes would beavailable since there are no additional levels).

Advancing outcomes might have various characteristics. As indicatedabove, in one embodiment, certain combinations of symbols appearingalong an active pay line are designated to be winning outcomes. Anadvancing outcome may be one of those winning outcomes where one or moreof the symbols of that outcome appear or occur in particular positions,such as positions of a top row of the set of symbols currently in play.In addition, an advancing outcome may comprise such an outcome plus atleast one or more other winning outcomes (without such outcomes havingto have symbols in particular locations other than along an active payline). The number of winning outcomes required to advance from aparticular level may vary, such as increasing based upon the level ofthe game (e.g. one winning outcome to advance from the first level, atleast two winning outcomes to advance from the second level, etc.).

Of course, other criteria may be applied. For example, the advancingoutcome might comprise a pay line which includes particular symbolpositions. In this regard it is noted that certain combinations ofsymbols along such a pay line might comprise an advancing combination,others might comprise a winning combination but not an advancingcombination, and yet other combinations along that same pay line mightcomprise losing combinations. Also, various pay lines may be defined.However, only certain pay lines and certain combinations of pay linesmay define advancing outcomes. Combinations of symbols along other paylines may simply be winning or losing (but not advancing) combinations.

As indicated, in the preferred embodiment each successive portion orlevel of the game “builds” on the prior portion or level by includingthe earlier symbols used therein. Thus, unlike other games where a firstset of symbols may be used and then another completely different secondset of symbols may then be used, in accordance with the inventionadditional symbols are used in each successive portion or level of thegame.

As indicated above, various symbols could be used in the game. Forexample, the symbols might comprise slot-type indicia. Card indiciamight be used, wherein a player attempts to form particular card hands.Of course, the symbols might comprise other indicia, including letters,numbers, graphics, color or the like.

As also indicated above, the particular number of symbols used and theirarrangement may vary. For example, the symbols could be arranged in rowsor columns of a matrix.

However, they might be arranged in circles or in a pyramid shape or thelike. Also, the number of symbols in the base level and those added insuccessive levels may vary. For example, in a pyramid configuration aplayer might attempt to receive an advancing combination from a base rowof 6 symbols. A row of 5 symbols might then be added in the next level,a row of 4 symbols in the next level, and so on. It is also noted thatthe manner or configuration in which symbols are added may vary. Forexample, rows of symbols might be added above or below a base set ofsymbols, or columns of symbols might be added to the left or to theright of a base set of symbols. In this manner, the set of symbols maybuild or grow in various directions or patterns, including randomly.

It will be appreciated that the various inventive game features may beused in various combinations and with other games or game features. Forexample, the “game advance” feature of the invention might be used inother types of games. Likewise, the symbol-matching feature and/or“building” feature might be used in other games or with other gamefeatures. Further various other features may be combined or integrated.For example, as with the first game embodiment detailed above, this gameembodiment may include features such as bonus awards, automatic advancefeatures (for example, one or more special symbols, if received in themost recent set of symbols, might automatically comprise an advancingoutcome), or other features.

While games of the invention may be played as wager-based games, it ispossible for the games to be played as amusement games. In some cases,such games may still require that a player provide payment to play thegame (though no monies may be awarded as prizes). In other embodiments,however, a player may not be required to make any payment or place anywager.

The games of the invention may be implemented via one or more gamingmachines 120, such as illustrated in FIG. 5. Such gaming machines 120might comprise casino-style gaming machines or personal computers or thelike. For example, when configured as a casino-style gaming machine, thegaming machine 120 includes a housing or cabinet 122 forenclosing/supporting various components of the gaming machine. Thehousing 122 may have a variety of configurations. In one embodiment, thehousing 122 is configured so the machine has an upright configuration.The machine 120 might also be configured as a slant-type, bar-top orhave other forms.

In one embodiment, the gaming machine 120 is configured as a video typegaming machine, the machine including at least one display 124 fordisplaying game information to a player. The gaming machine 120 mayinclude other means for providing information to a player. For example,speakers (not shown) or other devices may be provided for generatingsound associated with the game. The gaming machine 120 may also includelights, printed instructions and other displays/display devices.

In one embodiment, a player must make payment in order to be entitled toplay the game. Preferably, the game is presented as a wagering typegame, and a player must place a bet or wager in order to play the gamefor the opportunity to receive winnings. Preferably, if the player is awinner of the game, the player is provided an award, such as a monetarypayout (such as coins), credits representing monetary value, points ortangible prizes. As illustrated, the gaming machine 120 may include abill validator/acceptor 126 for accepting paper currency and a coinacceptor 128 for accepting coins. Other means of payment, such as acredit card reader, may be provided. An award of winnings in the form ofcoins may be paid to the player via a coin tray 130.

Preferably, the gaming machine 120 includes means for a player toprovide input. In one embodiment, this means comprises one or morebuttons. For example, a “spin” button 132 may be provided for permittinga player to start a game. One or more wager buttons 134 may be providedfor a player to select the amount to bet on a particular game. Othermeans of input may be provided, such as a touch-screen display and otherdevices now known or later developed.

A game controller (not shown) is provided for controlling the variousdevices of the gaming machine and for providing game information. Forexample, the game controller may be arranged to generate video and audiodata for presentation by the display and speakers of the gaming machine120. The game controller may be arranged to detect a signal from thecoin acceptor indicating the receipt of coins or from the bill validatorregarding accepted bills and for registering credits corresponding tothose inputs, for subtracting credits for wagers placed by a player, andfor causing a coin delivery mechanism to deliver coins from a coinhopper to the coin tray 130 for payment of winnings and/or return to aplayer of unwagered credits. Preferably, the one or more player inputdevices provide an output to the gaming controller for use in play ofthe game. For example, in response to a “bet one” input by a player, thegaming controller is preferably transmitted a signal which causes thegaming controller to initiate presentation of the game.

The gaming machine may include one or more random number generators forgenerating random game events and results. As indicated above, such arandom number generator might be utilized to generate the game symbolsfor the positions of a matrix, be utilized to generate the base symbols,and be utilized to select award values for each symbol position, amongother things.

It will be appreciated that the gaming machine 120 may have a variety ofconfigurations, and that the gaming machine 120 illustrated anddescribed above is but an example of a device for implementing the gameof the present invention. For example, in one or more embodiments, thegaming machine 120 may be associated with a network and receive gameinformation remotely and may transmit information, such as payout andgame play information, to a remote location. For example, a remotemaster controller may generate game information which is transmittedover a communication link to the gaming machine 120. That informationmay be utilized by a local controller or processor to present the game,such as by displaying game play data or information.

As indicated, in one embodiment, game information is displayed by avideo display 124 to a player. That display may be of a variety oftypes, including CRT, LCD, plasma and others. The gaming machine 120 mayalso include more than one video display.

In another embodiment, the gaming machine 120 may include one or morephysical reels capable of displaying symbols. In such a configuration,means are provided for rotating the physical reels. In one or moreembodiments, the means may comprise a mechanical linkage associated witha spin arm, with movement of the spin arm (a “pull”) by a user causingthe reels to spin. In such an arrangement, the reels are generallyallowed to free-wheel and then stop. In another embodiment,electronically controlled mechanisms are arranged to rotate and stopeach reel. Such mechanisms are well known to those of skill in the art.In this arrangement, actuation of the spin arm or depression a spinbutton causes a controller (not shown) to signal the activation of thespin mechanism associated with one or more of the reels. Preferably, thecontroller is arranged to either turn off the signal to the device(s)effecting the rotation of each or all of the reels or generates a signalfor activating a braking device, whereby the reels are stopped. As iswell known, the combinations of reel positions and their odds of hittingare associated with the controller, and the controller is arranged tostop the reels in a position displaying a combination of indicia asdetermined by the controller based on the combinations and odds. Theprincipal of such an arrangement is described in U.S. Pat. No. 4,448,419to Telnaes, which is incorporated herein by reference. For example, thebase symbols might be associated with spinning reels. Sets of basesymbols might be generated by spinning those reels.

The gaming machine 120 may have other configurations, including otherfeatures. For example, the gaming machine 120 may include a playertracking device, such as a card reader 138 and associated keypad 140.Such player tracking devices are well known and may permit the gameoperator to track play of players of the gaming machine. The trackedplay may be utilized to offer player bonuses or awards.

In one embodiment, the gaming machine 120 may be configured to dispensemedia, such as printed paper tickets, which have associated value. Forexample, winnings or unused credits may be returned to the player via aprinted ticket having value or associated value. In one embodiment, thegaming machine 120 might also be configured to accept such media forproviding credit for game play. Such systems are well known and thus notdescribed in detail herein.

As indicated, in a preferred embodiment, the games of the invention areplayed as wagering type games in which a player must place a wager inorder to play the game for an opportunity of winnings. However, in otherembodiments, the games may be played for fun or prizes. In such event,the player may be permitted to play the game for free or may be requiredto make payment to play the game.

As indicated above, a player may provide value to the gaming machine 120or machine operator in a number of ways, including with coins or bills.The player might also be permitted to provide value remotely. Valueprovided to the gaming machine 120 may be represented as credits. Eachcredit may have an associated monetary value.

The gaming system might include additional elements. As indicated above,the game may implement various progressive jackpots. In one embodiment,a plurality of gaming machines may be linked to one or more progressiveservers.
